Programmable timer remote for Canon EOS cameras My first "serious" project (besides playing with lights, as my friend Alan put it) is (More) My first "serious" project (besides playing with lights, as my friend Alan put it) is almost done.
This is going to be a configurable remote for my Canon EOS 350D / Digital Rebel XT (and possibly for all the cameras of that series). The shutter is closed when two lines of the 2.5 mm stereo jack are shorted; this is achieved by using the relay.
My remote has two modes of operation, chosen through a simple deviator used as a switch: time lapse and bulb.
In time lapse mode, it counts down to the specified interval and quickly closes the relay switch to fire the camera's shutter, then starts counting again. In bulb mode, it immediately closes the relay switch and starts counting; when the counter reaches zero, the relay switch is opened (the camera's shutter opens too) and it goes back to idle mode.
The interval is defined in seconds and can be any multiple of 5 between 5 and 995 (that's over 16 and half minutes, and it's close to the camera B mode limit of 999 seconds). It is changed through two buttons (UP and DOWN).
The third button, ENABLE, starts or stops the counter; I had originally thought about using a deviator switch for it, but I realized that the counter should have been stoppable by software too, therefore a push-button proved most useful for that.
In this video, the shutter control is replaced by a green LED as I currently lack a wire long enough for my needs. I will solder it to the connector tomorrow, and test it in the field. Hopefully my camera won't be fried by it. ;)

Canon EOS - 1000D 450D 500D Live View Shooting Take advantage of the big, bright 2.5-inch LCD monitor to compose photos with Live View shooting. (More) Take advantage of the big, bright 2.5-inch LCD monitor to compose photos with Live View shooting. This convenient alternative to the viewfinder is almost like using a compact digital camera. It is particularly suited for low- and high-angle shots or when using a tripod. Live View shooting is also great for verifying exposure and depth of field, giving you the opportunity to confirm both on the monitor before taking the picture. For compositions requiring close inspection, you can zoom 5x or ... (Less)
